FRED B. STOCKMANN, OF CINCINNATI, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS,TO MARGARET FRELINGER, OF NEWPORT, KENTUCKY.

AGITATOB 0R STIRRER FOR PAINT-BARBELS AND THE LIKE.

To all whom 'it may concern:

Be it known that I, FRED B. S'rookMAN N, a citizen of the United Statesof America, and a resident of Cincinnati, in the county of Hamilton andState of Ohio, have invented a certain new and useful Improvement inAgitators or Stirrers for Paint-Barrels and the Like, of which thefollowing is a speci fication.

This invention relates to paint mixers, or, more particularly speaking,to the agitating or stirring devices used in barrels, kegs, cans or likereceptacles for paint that has been already mixed, or for other liquidcompounds that contain heavy matter or sediment that has a tendency tosettle to the bottom when at rest.

The object of the invention is to provide a stirring blade or paddle ofa single sheet of metal or other suitable material that is not likely toaffect or be affected by the contents of the receptacle, such singlepiece of material being bent and shaped into form with due considerationfor both lightness and strength and, also, for use in causing thesettlings to readily rise in the liquid for thorough admixture.

In the single sheet of drawings, forming a part of this specification,Figure 1 is a vertical section of a barrel showing my im provedagitating or stirring device in operative position therein; Fig. 2, afragmentary, vertical section, partly in elevation, showing thebottom-head of the barrel (omitting the barrel itself), the lowerportion of the upright shaft of the device, the lower bearing for saidshaft mounted on said bottom-head and the stirring-blade mounted on saidlower portion of the upright shaft, all on a somewhat larger scale thanthat of the same parts seen in Fig. 1; Fig. 3, a plan view of thestirring-blade that forms the principal feature of my invention herein,such blade bein detached from all the other parts of the deviceexcepting the upright shaft, the latter being shown in cross-section;Fig. 4, a plan View, on a reduced scale, showing the blank strip orpiece of sheet-metal used in formin' my improved stirring-blade, thedottedlines indicating those on which the blade is bent and shaped intothe form seen in said Fi 3; and Fig. 5, a fragmentary section of t ehead or to of the barrel showing a safety-plug used in the centerthereof for closing the shaft aperture when the Specification of LettersPatent.

hand-crank has been removed and when the barrel is to be closed andhandled.

In these views, 1 indicates the barrel or receptacle for the paint orother solution to be held therein.

2 indicates the bottom-head and 8 thetophead of the barrel, the top-headhaving a central aperture 4 and the bottom-head having a central step orraised bearing-piece 5, the latter being suitably secured by means ofscrews or the like 6 on the inner face of the said bottom-head.

7 indicates an upright axial shaft centrally-disposed in the barrel,with its lower reduced end 8 bearing in the central aperture in theraised portion of the bearing 5 and passing upward through the centralaperture 4 in the top 3, a centrally-perforated plate 9 being securedconcentric to the outer face of the head 3 over the aperture 4, as bestseen in Fig. 1. The plate 9 is removably-attached in place by screws orthe like and forms a wearing surface for the said aperture 4 in the topof the barrel and so that the upper part of the shaft turns free of saidaperture 4.

10 is a hand-crank removably-attached to the upper end of the shaft 7,for driving the latter.

A cotter-pin 11 is placed in the lower re duoed end 8 of the shaft toprevent the latter becoming disengaged from the bearing 5 in use. Thiscotter-pin enables the ready separation of the shaft from the bearing 5when desired and is readily inserted owing to the opening provided inthe raised portion of said bearing. The lower end of the shaft is raisedabove the inner face of the bottom of the barrel so that there is noundue wear or friction.

The most important feature of my inven tion herein lies in theconstruction of the paddle or agitator. This agitator is a horizontalone and is made of a single sheet of metal cut into the form seen in theblank m, Fig. 4. This blank is split at y, perforated with a small holeat a, and, also, perforated with a square hole at s, the purposes ofwhich will be now described.

The agitator blade or paddle is composed of the body portion 12 havingat its opposite ends the flaring arms or wings 13 and, also, havingalong its horizontal upper edge an integral flange 14 bent laterallyoutward horizontally.

In Fig. 4, it will be seen that the flange 14 is bent on the dotted-line14" and the flared wings 13 are shaped along the oblique dotted-lines 13The shaft 7 is preferably square in crosssection and passes downwardlythrough the square aperture 8 in the flanged portion 14 of the blade andthence downward in contact with the body portion 12 of the blade, to andthrough an opening or guide-way provided by upsetting oroutwardly-turning the metal y in the split portion y of the blank. Thelower edge of the blade .is elevated slightly above the raised portionof the bearing 5, as best seen in Fig. 2, so as to properly clear saidraised portion of the bearing in rot-at ing, and a rivet 15 is providedto suitably attach the blade in place on the shaft, and, also, as bestseen in said Fig. 2, the said rivet passing through the perforation z ofthe blank m after the blank has been duly shaped.

It is important that the blade be made of a single sheet of metal andprovided with the flange 14:, together with the integral wings 13, 13,so that .its manufacture is simple and economical and so that there areno loose parts to get out of order or become detached and, also, so thatsuch blade can be readily attached in place by means of a single rivetat the lower end of the shaft and securely held in position free fromlateral or torsional movement on the shaft and is adapted to stir andforce the sediment or heavy material from the bottom of the receptacleinto solution or thorough circulation with theliquid contents of suchreceptacle.

The safety-plug, seen in Fig. 5, is another important feature of theinvention herein, for the reason that it is to be used when thehand-crank 10 is removed and the barrel is to be tightly closed for anydesired handling thereof. This safety-plug is composed of a closed head16 having a flange or base 17 and a lower, extended screw-threaded shank18, such shank being adapted to be readily turned or screwed into theaperture 4 of the top-head 3 when plate 9 has been removed, the hollowor elongated cavity 19 of the plug being adapted to receive the upperend of the shaft 7 and to hold the stirring mechanism in properposition. None of the contents of the barrel can escape when this plugis in place and it is readily removed when it is desired to use thestirring or agitating devices.

An outlet-faucet 20 is provided at the bottom of the barrel for use inwithdrawing the contents at will and is a feature common topaint-mixers.

It is obvious that a number of addles or blades such as the one shown,can e mounted on the shaft 7 at suitable intervals apart l above theblade already shown in Fig. 1, for the purpose of expediting theadmixture or circulation of the contents, especially when the settlingsare of a very heavy nature, such as is paint itself that is mostlyconcerned herein. A series of paddles or blades constructed on my plancan be readily attached on the shaft and at comparatively small expensetaking into consideration the effective result accomplished on saidheavier ingredients.

I claim:

1. A stirrer or agitator device for paint barrels or the like, the samecomprising a single sheet of metal having a flat body portion, madeintegral flaring wing portions at the opposite ends of such body portionbut within the length thereof and a horizontal flange orforwardly-projecting portion along the upper edge of said body portion.
